Post by ruobian on Analog Input Delay Timer
CODESYS Forge

(Post)
Hello there, I am new here and in programming. I need help with the basics. I am trying to do what I mentioned in the title. I have an analog input. So I have a real or integer data type value. I want to delay it. TON and TOF only work with bool. I think there is a function block that has two inputs, 1 for real or int and 1 for bool. And if bool is true, it will give the output as real or int. I don't know but I need something like this. Actually, it is not exactly like that. In other words, it will not show the real value at the input at the output after a certain period of time. I want it to show the real value from 2 seconds ago continuously. The purpose of doing this is to compare the real value I received with the value from 2 seconds ago and find out whether it went up or down. I am using only FBD. Please help me with this. Thanks in advance.

Hi kdkwhite, for Word you still can use suggested code by using a union structure and crack down your Word to two byte as bellow: TYPE CrackWordToByte : UNION InWord : WORD; OutBytes : ARRAY [0..1] OF BYTE; END_UNION END_TYPE then define your variable as this type: udInput : CrackWordToByte; now assign your Word variable input to InWord and send OutBytes[x] to the mentioned method: udInput.InWord := WordVariableInput; Input := udInput.OutBytes[x]; Regarding your question about the code: actually 48 is ascii code of "0" and while 65 is the ascii code of "A" so in above code 55 + 10 would be 65.

Dear all, I've just started to migrate some of my ancient projects to SP20. There is one strange error (?) I have noticed so far. In a method call, depending on the circumstances I would like to return reference to an object, or an invalid reference: METHOD Add_EVT_OUT : REFERENCE TO FB_MSG VAR END_VAR IF __ISVALIDREF(refMSG_Entry) THEN Add_EVT_OUT REF= MANAGER.AddMsg_EVT_OUT( refMSG_Entry, _Get_EVT_Message(MSG_EVENT.OUT), _Get_EVT_AddCode(MSG_EVENT.OUT) )^; ELSE Add_EVT_OUT := 0; END_IF So far setting a reference variable to 0, did this. But now, the expression Add_EVT_OUT := 0; gives an error: [ERROR] DB_WTP_370: Add_EVT_ACK MSG_TRIGGER_EXT: C0032: Cannot convert type 'BIT' to type 'REFERENCE TO FB_MSG' Naturally... I can write: Add_EVT_OUT := DWORD#0; But is this the correct way? Is there any constant I could use instead, like "NULL"? Or this is totally wrong and to be avoided?

Hi We upgraded our ptoject from 3.5.19 to 3.5.20 but we get an error message in the latest version. We made our own trend function and its related to this we get error message: Trend_Menu Device: PLC Logic: Application: C0032: Cannot convert type 'RTS_SYSTIMEDATE(systimertc, 3.5.20.0 (system))' to type 'RTS_SYSTIMEDATE(systimertc, 3.5.17.0 (system))' The variables are defined as follow: start : SysTimeRtc.SYSTIMEDATE; end : SysTimeRtc.SYSTIMEDATE; The code that creates the error is the variable start and end IF xAssign THEN xAssign := FALSE; xPanEnable := FALSE; xZoomEnable := FALSE; drs.liFrom := VisuTrendStorageAccess.TrendStorageConvertToTimestamp(start, 0 (us)); drs.liTo := VisuTrendStorageAccess.TrendStorageConvertToTimestamp(end, 0 (us)); drs.m_itfDateRangeSelectorClient.SetCurrentRange(drs.liFrom, drs.liTo); END_IF I cant understand really what the error message means and what can be the cause of the error? It compiles fine in dthe older codesys 3.5.19. If anyone has some experience of this please help us out? We must upgrade due to the new licenses. Thanks

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
